Hi guys, I'm find a strange behavior with an IP Phone 7921 in g.729 with callmanager 4.2(1). My setting on CCM is: Preferred G729 Millisecond Packet Size* 60. With this setting a take one way audio conversation only to 7921, other IP Phone work good. When I'm setting to 50ms the call work correctly. Someone know something about this problem? The 7921 doen't support 60ms of speetch per packet?
Check the access point to see that the transmit power setting matches the transmit power setting on the phone. One-way audio is common when the access point power setting is greater (100mW) than that of the phone (20mW).
